The answer would be 7. Another way to think of it is subtract 40-33. That gets you 7.
Glass bottles =total number of bottles - numeber of bottle of plastic
gass bottles=50-19=31 bottles of glass.
percent of the bottles are glass=(number of bottles of glass*100%) / total number of bottles.
percent of the glass bottles=(31 bottles * 100%) / 50 bottles=62%
Answer: the percent of the bottles of glas is 62%
Answer:
Road C is 1.5 mi east of Road A
Step-by-step explanation:
we know that
Road B is 4.6 mi east of Road A
Road C is 3.1 mi west of Road B
so
Road C is between Road A and Road B
AB=4.6 miles
CB=3.1 miles
AB=AC+CB
Solve for AC
AC=AB-CB
AC=4.6-3.1=1.5 miles
therefore
Road C is 1.5 mi east of Road A
So for this, I will be using the substitution method. Firstly, subtract both sides in the second equation by 2x: 
Next, substitute y in the first equation with 7-2x, then solve for x from there:

Now that we got x, substitute it into either equation to solve for y:

In short, x = 1/2 and y = 6.
Answer:
(4,11)
Step-by-step explanation:
y=2x+3
y=5x-9
the first equation is equal to the second equation so
2x+3=5x-9
put like terms together
2x-5x= -9-3
-3x= -12
divide both sides by -3
.•.x=4
now, use the value of x to find the value of y like this:
y=2x+3 (x=4)
y=2(4)+3
y=8+3
y=11
therefore, the two lines intersect at the point (4,11)
